Permanent Mold Center Sections: The Strongest Castings Available
Our new Permanent Mold 10-inch Quick Change raises the bar for strength and reliability higher than ever. The center section's been redesigned for added strength (without added weight), but the biggest advantage is the state-of-the-art Permanent Mold casting, which has stronger mechanical properties than the sand cast process used for all other quick changes on the market.
